Comparison of mass accretion rate acc, mass loss rate of the O star wind, and Eddington accretion rate of the BH Edd during the BH+O binary phase modelled from the 17 observed progenitor WR+O binaries for (β,η,γ±) = (0.8,1/3,1). The upper and lower panels present acc/wind and acc/Edd, respectively. The colour coding in the legend denotes the 17 WR+O systems that are expected to form BH+O binaries.
